Quipu/khipu: different colored threads, used to track trade items from coast to Andean inland communities.

Fishnet: different colored threads, to camouflage in water.


The find at Laguna de las Condores confirmed that quipus served an
objective function of record keeping in the bureaucracy of Andean
city-states several hundred years before the Inca. The Wari polity
existed from 600 to 1000 ad, having owed its existence to the
trading of luxury goods for the ample seafood resources of the
coast. A quipu could be transported and read from one village to
another, and the redundancies reduced error.
